HINGE.

SPECIFICATION forming part of Letters Patent No. 793,521, dated June 27, 1905.

Application filed July 13,1904. Serial No. 216,316.

To all whmn, it may concern.-

Be it known that I, FRED L. HAWKINS, of Gardner, in the county of WVorccster and State of Massachusetts, have invented certain new 5 and useful Improvements in Hinges; and I. hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

I This invention has reference to improvements in hinges, and particularly to improvements in shutter-hinges.

One object of the invention is to so construct a hinge that the swingingmember thereof may I be locked to the stationary member.

Another object of the invention is to so construct a hinge comprising a swinging member adapted to be locked to a lixed member that the swinging member cannot be wholly disengaged from the pintle of the fixed member except when particularly positioned for such purpose.

The invention consists in such novel features of construction and combination of parts 5 as shall hereinafter be more fully described,.

and pointed out in the claims.

Figure 1 represents a side elevation of one form of the improved hinge. Fig. Q-represents a plan view of the same. Fig. 3 repre- 3 sents a side elevation of a modified form of the hinge. this modification.

Similar characters of reference designate corresponding parts throughout.

In carrying this invention into practice my desire has been to so construct a hinge comprising a fixed pintle member and a pivoted member that the pivoted member could be automatically locked in the desired position relat tive to the fixed member and could readily be released from said locked position by simply lifting the pivoted member, provision being made to limit this upward movement of the pivoted member, so that it could not at the t5 point of said release be wholly lifted from the pintle.

As shown in the drawings, in its preferred form the improved hinge comprises the Fig. 4 represents a plan view of bracket 5, of any usual form and construction,

adapted to be secured in place to sustain the 50 pivoted hinge member and the shutter or other object carried by the pivoted member. This bracket 5 has the locking-tooth 6 and the pintle 7 positioned at a distance from said tooth and having the radially-extending shoul- 5 5 der 8, having the upper rounded end 9 and the straight lower end 10. The pivoted member comprises a horizontally-disposed plate 11 and the vertical securing-plate 12, integral therewith, adapted to be secured to the object, a shutter, or like movable object which it is desired to pivotally support. Preferably at the periphery of the plate 11 are formed a series of engagements 1313, herein shown as notches, which are designed to receive one end of the tooth 6, and at the axis of the plate 11 is formed a perforation 14, having the lateral slot 15 extending at an angle with the notches As shown in full lines in Figs. 1 and 2, the plate 11 is locked against rotation by the engagement of the teeth 6 by the notch 13. The plate 11 is released from this engagement by lifting the plate to the position shown in dotted lines in Fig. 1 and rotating the plate'on its pintle, the peripheral portion of the plate riding over the tooth 6 in this rotation until the next notch 13 is brought opposite the tooth 6, when the tooth will be received thereby and the plate 11 will again be locked from rotation. Undue upward movement of the plate 11 in the disengagement of one of its notches 13 from the tooth 6 is prevented by the shoulder 8 on the pintle 7, as the extension 15 of the perforation 14 is out of registration 5 In the modification illustrated in Figs. 3 and 41 of the drawings the bracket 5, of any usual construction, has the locking-tooth 6 and the pintle 7. Instead, however, of placing the locking-shoulder on the pintle 7 the rear portion of the tooth 6 is extended upward and outward toward the pintle to form the tongue 8, which extends inward toward the pintle 7 a greater distance than does the tooth 6, a space being formed between the upper edge of the tooth 6 and said tongue to provide clearance for the pivoted member when the same is raised above said tooth. This tongue 8 is also narrower than the tooth 6, as is shown in Fig. 4:. The pivoted member of this modified form comprises the circular plate 11, having the securing member 12 and furnished at its edge with the notches 13 13 and 14:, the notches 13 13 being designed at times to engage with the end portion of the tooth 6, while the notch 14, being narrower than said tooth, will not engage therewith, this latter notch 14 being of a length and width which will permit it to pass over the tongue when the plate 11 is suitably positioned for such passage. The plate 11 has also an axial perforation adapted to work on the pintle 7'.

hen the plate 11 is raised from the position shown in full lines in Fig. 3 to that indicated in dotted lines therein, said plate can be readily rotated on the pintle 7 until one of the notches 13 is again brought into registration With the tooth 6'; but said plate 11 cannot be wholly lifted from said pintle unless the notch 14: is brought into registration with the tongue 8.

By the location of the'securing member 12 or 12' in close proximity to the axis on which the plate 11 or 11 rotates the edge of the object a, secured to said member, is located close to the bracket both in the open and closed positions, while the leverage secured by the extension of the plate 11 or 11 from the pintle to the tooth 6 or 6 tends to resist the movement of said article under accidental pressure, or, in the case of a shutter, against wind-pressure.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A hinge comprising a bracket adapted to be fixed in position and having a pintle and a pair of locking members arranged in line but at different heights, and a circular plate pivoted on said pintle and having a series of notches in its periphery, adapted to engage one of said locking members, and a passage,

extending at an angle with said notches, adapted to pass over the other of said locking members when brought into registration therewith whereby the pivoted plate maybe moved vertically from its engagement with the pintle.

2. The combination with the bracket 5 having the locking member 6 and the pintle 7 at a distance from said locking member, and having the shoulder 8 extending in line with the member 6, of a pivoted member having the horiZontally-disposed plate 11- and the vertical securing-plate 12 the plate 11 having the peripherally-disposed notches 13 13 and the axially-disposed perforation 14: having the lateral slot 15 out of line with the notches 13 13, as and for the purpose described.
